After much speculation, TIDAL has officially announced the lineup for its second annual TIDAL X: 1015 show. As expected, Beyonce will headline the show but there are some other big-name acts topping the bill. Rap superstar Nicki Minaj and R&B powerhouse Alicia Keys are also set to rock the mic.

New York radio personality Angie Martinez is the host of this star-studded benefit concert, which takes place on Oct. 15 at the Barclays Center in Brooklyn, N.Y. If you are a TIDAL subscriber and/or American Express cardholder, you can cop pre-sale tickets right now. Tickets for the general public will go on sale Monday (Sept. 26).

Proceeds from the event will go to the Robin Hood organization, New York's largest poverty-fighting organization, which funds and creates programs for schools in impoverished neighborhoods. Last year’s TIDAL X: 1020 show raised more than $1.5 million.
